SHAFT-BEARING.

Specification of Letters Patent.

Patented 33ers. 10, 1907..

Application filed January 17.19105. Serial No. 241474.

all whom it may-concern: i Be it known that 1,.-ADELBERT SAUER, acitizen of the United States, and resident of Pittsburg, county ofAllegheny and State of Pennsylvania, have invented certain new l anduseful Improvements in'Shait-Bearin'gs,

a suitable support 13.

of 'which the following is 'a iull, clear, and

exact specification, reference being had to the accom anyingdraw'ingshillustrating a bearing em odying my invention, wherein- Figure1 is a vertical longitudinal section through-thebearing; Fig. 2 is atransverse section on line 2 2, indicated in Fig. 1; Fig. 3 is atransverse section on line 8 8, indicated inFig. 1; Fig. 4 shows thesleeve Jfor carrying the bearingb'locks and Fig. 5 an end view of thesame; Fig. G is a transverse longitudinal section through a form'ofbearing having means for adjusting the bearing blocks at both ends ofthe bearing. This invention relates to adjustable shai bearings and hasfor its object to provide means whereby a set of bearing members orblocks can be adjusted in a radial direction to 4compensate for wear,"and to insure a proper alinement of the' shaft. -f

Referring now to Figs. 1, 2, 3, 4 and 5,- the casing or shell 12 of thebearing is carried by On, the shaft 14 is loosely fitted a sleeve ,15,shown-se arately in Fig. 4', provided with lslots 16. n these slots areinserted the bearing-blocks 17, ,to slide freely therein and so as to beadjustable relatively to shaft 14. At one end of the shell 12, a thimble18 is placed between the shell and the bearing blocks 17 the engagingsurfaces between these three parts being' so arrangedthat according tothe position of the thimble Y18, the blocks' 17 are brought nearery toor farther from the shaft 14. The

preferred construction for this purpose is toV make the bearing blocks17 Wedge-shaped, their outer faces engaging-the thimble 18 beingat anangle to the 'axiaof the shaft,

rounded and tapering towards the end of" shell 12 engaging the thimble18.' Thus the outer faces of the four blocks 17 are parts of' The boreofthimble 18 is also madef Itapering or conical, correspondingly tothe*-faces of blocks 17. The preferred" means for moving blocks outer thethimble 18 upon the 17 `to thereby move' them towards the shaft is byscrew-threading the thimble 18y externally, andthe shell l12 internally.The outer shape of thimble 18 is cylindrical, and

engages the thimble vand it 'then moves inwardly when rotated. By thusrotating the thimble 18, the blocks 17 are accurately adjusted to insurea proper engagement with the shaft and compensate 'for wear. For moreconvenient turning of thethimble 18, an annular iiange 19 is provided atits outer end. This enables the thimble to be engaged with a'spanner orwrench.

Threaded ring 20se-t on thethimble 18 may be used to screw upfagainstthe end of the shell, after the thimble has been adjusted, as a locknut, to prevent its displace ment. Another means provided for lockingthe thimble 18 comprises the annular flange 21 on the end of the sleeve15, through which,

pass a number of'bolts 22, that bear on the flange 19 ofthe thimble 18;nuts 23 on the bolts on each side of the flange, serve toiorce the boltsagainst the flange and look them in place, lthus securing the thimble inposition l eating oil maybe drawn off from the bottom 'of shell 12 byanother pipe, (as shown in Fig.

6' and designated by numeral 28,) and fed into the tank by a pump orother such device. In `Fig. 6 is shown a modified form' of my improvedbearing, inwhich each of the bearing vblocks is provided with separatemeans of adjustment at each end of the bearing'. It

ycom r1`ses.a supporting shell 12a, inside of Wl11c, is a sleeve 15ahaving longitudinal slotswherein'thebearing blocks 17a are inserted.Their outer faces are rounded and rconically inclined to both, ends,.the blocks lthus j forming a-double'- ended cone. The

outer .faces of thebl'ocks are enga ed by the gles 18E. at V Thimbles1.8a are threaded into the shell 12a like the thimble v18 in the otherconstruction, and their bores are correspondingly conical to engage theblocks 17 ik. By these means each end of the blocks 1 7i'fcan beadjusted ontoeach end of the shaft. This bearing is. also provided withan oil chamber. 'To prevent escape of l sleeve loosely tted ont-heshaft, bearing,

thezoil, packing rings 30 of suitable material are placed at each end ofthe sleeve 15a and secured in place by flanged collars 31. Bolts 32secured in the adjustable thimbles 18a pass through bores 33 provided inthe anges A of collars 31, and lock nuts 34, two on each bolt, engagethe flange from each side thus securing the collars 31- in permanentposition relatively to the other parts of the bearing.

I claim as my invention z- 1. A shaft bearing lcomprising a shellinteriorlyA screw-threaded at one end, a slotted sleeve loosely itted onthe shaft, wedgeshaped bearing blocks set in the slots, athirnble'having its bore taperin and thereby engaging the blocks', thethimb e being eXteriorly screwthreaded and thereby engaging the threadedshell, there being a flange on one end of the sleeve, bolts secured tothe ange and arranged to engage the thimble,

and lock nuts on the bolts engaging they flange, substantially as hereinshown and described. V

. 2. A shaft bearing comprising a slotted blocks set in the slots, theouter faces of the blocks bein inclined towards each end, a shell, thimbes one at each end ofthe shell located between the inclined faces ofthebearing blocks .and theshell, and provided with means for moving thethirn'bles to adjust the blocks, substantially as herein shown anddescribed. l

3. A shaft bearing comprising a shell interiorly screw-threaded at eachend portion, a slotted sleeve loosely fitted on the shaft,

bearing blocks set in the slots, the outer faces of the blocks beinginclined towards each end; thiinbles, one at each end ofthe shell,having their bore made tapering and engaging the blocks by their inclmedfaces, the thinibles being externally screw-threaded and therebyengaging the threaded shell,

vsubstantially as herein Shown and described.
